MultiByte International Characters
Most languages use a single byte of eight bits to represent a character, e.g. English,
French, German, Hebrew, Russian, Thai, etc.
Multibyte character fonts require more than the usual eight bits to specify a
character. This occurs when a language has more than 256 characters (2
8
) in a font.
For example, Chinese fonts contain several thousand characters. Other multibyte
languages include Japanese and Korean.
There are two separate applications with multibyte characters – static text on buttons
and indirect text on buttons. No Isys touchpanel firmware changes are required in
either case.
Indirect text on a button is entered in VTPro-e and the actual string to be displayed is
entered in SIMPL Windows. As of this publication date only completely single byte
or completely multibyte strings may be entered or they will not be compiled
correctly in SIMPL Windows. In other words, you cannot enter Chinese characters
interspersed with numbers. You can enter Chinese characters or numbers in separate
strings or you can pad each number with “\x00” to make it multibyte and then
combine it with Chinese characters in the same string.
Of course, you can always use the workaround of showing a graphic that displays the
string but it is not dynamic. To compile and use multibyte characters it is essential
that the operating system understand the language. Windows XP, Vista and 7 are
available in many international languages and add-on software is available for other
versions of Windows.
